August Alsina performed at an anti-violence-themed concert this weekend in St. Louis where an altercation between August and the show's promoter, Loose Cannon Slim, broke out backstage at the event. TMZ obtained footage of the incident, which shows August and his crew arguing with the promoters before the eventual fight broke out, where August is seen on camera kicking a man on the ground during the fight. 

The promoters were reportedly upset that August had shown up late for his performance at the show, which was called "State of Emergency 2," with all proceeds going towards the "Put Down the Pistol" program. Despite the incident, it appears that August still did perform at the concert. Footage of the fight can be viewed above.
